As we previously reported, the iPhone Dev Team has updated both their Redsn0w (for Windows and Mac OS X) and PwnageTool (exclusive for Mac OS X) to enable iOS jailbreakers to jailbreak the recently released iOS 4.3.1 on iPhone 4 (GSM model), iPhone 3GS, iPod Touch 4G, iPod Touch 3G, iPad 1, and AppleTV 2G. Unfortunately, there’s no jailbreak support for iPad 2 at the moment.

Both Redsn0w 0.9.6 RC9 and PwnageTool 4.3 both utilize an exploit discovered by Stefan Esser, a German iPhone hacker and iOS security specialist and the main man behind the antid0te framework, to untethered jailbreak the iOS 4.3.1.

However, if you are an iPhone unlocker who depend on Ultrasn0w unlock, you have to wait a little as the iPhone Dev Team still working on to fix the Utrasn0w and some bugs between iOS 4.3.1 and the older basebands required for carrier unlock. If you don’t care about unlocking your iPhone form its contracted mobile phone carrier, then it is recommended to use Redsn0w 0.9.6 RC9 as it features a very easy jailbreak method. So if you are an iPhone unlocker, then you can jailbreak your iOS using PwnageTool 4.3 for Mac OS X. You can follow our step-by-step guide posted below to successfully jailbreak your iPhone (as well as other iOS devices) running on iOS 4.3.

Step 5: Now, you have to put your iOS device into DFU mode by following the on-screen instruction:
• Hold Power and Home buttons for 10 seconds
• Now release the Power button but continue holding the Home button for 10 more seconds
• You device should now be in DFU mode

Step 6: When done, PwnageTool will tell you to go and restore in iTunes. Launch your iTunes (it will recognize a device in recovery mode), Click OK to continue. Hold the “Alt/Option” key and click “Restore” at the same time to restore your custom firmware. DO NOT click “Restore” without holding the “Alt/Option” key! A dialog box will pop up and you’ll be able to choose the custom IPSW file you created.

That’s it you’re done! You can now enjoy your completely jailbroken iPhone. Just wait for the Dev Team to fix the Ultrasn0w 1.2or for the Ultrasn0w 1.3, then unlock your iPhone by following our step-by-step guide to unlock iPhone using Ultrasn0w posted here. Stay tuned for more iPhone jailbreak and news.
